Answer: Set up an S3 bucket event notification to directly invoke an AWS Lambda function for inserting records into DynamoDB.
The correct answer is B. To achieve real-time record insertion into an Amazon DynamoDB table when a new file is added to an Amazon S3 bucket, you can configure an S3 event notification to directly invoke an AWS Lambda function. The Lambda function can then insert the records into DynamoDB. This approach is efficient and ensures that the record is inserted as soon as the file is uploaded. Option A is incorrect because using Amazon EventBridge adds unnecessary complexity. Option C is incorrect because polling the S3 bucket is inefficient. Option D is incorrect because a cron job does not provide real-time operation.
